Indonesia police on Tuesday released a series of files from slain terror leader Noordin Mohammed Top’s laptop showing detailed and chillingly nonchalant planning behind the July bombings in Jakarta.

Videos on the computer seized in the Central Java raid this month that killed Noordin, 41, show suicide bombers and other militants discussing and making preparations for the July 17 attacks, which killed seven people.

In one video, the two suicide bombers, Dani Dwi Permana, 18, and Nana Ikhwan Maulana, 28, are seen doing stretches near an empty lot in front of the targeted JW Marriott and Ritz-Carlton hotels.

In another video, the bombers and hotel florist Ibrohim — who police say helped stage the attack from the inside — picnic on biscuits and apples on the grass in front of the hotels.

Syaifudin Jaelani, a fourth militant still on the run from police, says off camera: “America, destroyed; Australia, destroyed; Indonesia, destroyed.”

In yet another clip, teenage bomber Dani is seen in front of the hotels saying: “This is not suicide, this is a good deed.” “We see how they are preparing themselves, how they have filmed their plans and their surveys of targets through their own eyes,” police spokesman Nanan Soekarna said.
